JOHN PLAYER, OF DUNKIRK, NEW YORK, ASSIGNOR TO AMERICAN LOCOMO- TIVECOMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

REVERSE-LEVER.

SEECIFICATION forming part of Letters Patent No. 696,482, dated April 1,1902.

Application filed July 23,1901- To all whom, it may concern:

Be it known that I, JOHN PLAYER, of Dnnkirk, in the county of Chautauquaand State of New York, have invented a certain new and usefulImprovement in Reverse-Levers,

of which improvement the following is a specification. m

My invention relates to reverse-levers employed on locomotive-engines ofthe wide or widened fire-box type; and its object is to provide areverse-lever which can be located and operated in rear of the fire-boxand which shall be of simpler and less expensive coustruction thanappliances heretofore used for the same purpose.

To this end my invention, generally stated, consists in the combinationof an integral body which is provided with a bearing-pin socket at itslower end, areach-rod-pin socket located at one side of its upper endand projectiug outwardly beyond the bearing-pin socket, and a lever-armfixed to the upper end of the body on the side thereof opposite thereach-rod-pin socket.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a diagrammatic side view of alocomotiveeugine, illustrating an application of my in- 0 vention; Fig.2, a similar end view of the same; Fig. 3, a transverse section at theline a a of Fig. 1; Fig. 4, a rear View, on an enlarged scale, of theappliance complete; Fig.

5, a similar View, on a further-enlarged scale, 5 of the reverse-leverbody as seen from the rear; Figs. 6 and 7, views in elevation of thesame as seen from the inner and the outer side, respectively; and Fig. 8a horizontal section at the line b b of Fig. 5.

My invention is herein exemplified as applied in connection with alocomotive-engine of recent design and construction which is of thehigh-speed, heavy-draft, wide-fire-box type. The locomotive is supportedon three 5 pairs of driving-wheels l of comparatively large diameter, apair of leading-wheels 2, and a pair of trailing wheels 3. The boiler 4is provided with a wide fire-box 5, by which is meant a fire-box whichis of greater width than the distance between the inside faces of thedriving-wheels, and the cab 5 is lo- Serial No. 69,375. (No model.)

cated above the fire-box and extended in rear thereof in order to enablethe engineer and fireman to be both stationed behind the firebox and toperform their duties in the same inclosure. The lifting-shaft ortumblingshaft 6, by which the valve-links 7 are raised and lowered toeffect the reversal of the direction of movement of the engine and thevariation of the point of cut-off as from time to time required, isjournaled in hearings on the frames 8 between the forward and middlepairs of driving-wheels and is actuated by a reach-rod 9, the forwardend of which is coupled to a tumbling-shaft lever 10 and the rear end tothe reverse-lever. With a cab located as above described it is desirablethat the full traverse of the reverse-lever should be made in rear ofthe fire-box in order to facilitate the operations performed by theengineer, and to enable this to be done and the connection of thereverse-lever with the tumbling-shaft to be properly effected a specialconstruction of reverse-lever becomes indispensable in wide-fireboxengines having a cab which extends behind the fire-box. My inventionprovides an appliance which has been shown in practice to besatisfactorily adapted to the structural and operative conditions forwhich it is designed and which is of simple, durable, and inexpensiveconstruction.

In the specific embodiment of my inven tion which is herein exemplifiedthe complete reverse-lever is composed of an integral body 11 and alever-arn1 12, fixed thereto. The body 11 is preferably a steel castingin the form of a plate, the upper end of which is outwardly or laterallyextended at one side relatively to its lower end and which may have oneor more openings 14 cored in it to reduce its weight. A bearing-pinsocket 15 for the reception of a fixed bearingpin 16, upon which thereverse-lever is fitted to traverse, is formed on the lower end of thebody 11, and strengthening-flanges 17 are preferably cast upon its topand its inner and outer sides. The lever arm 12 is preferably, as shown,detachably connected to the body 11, and to this end the body 11 isupwardly extended at its top, on its inner side, such extension forminga lever-arm seat or face 18, which is provided with vertical sideflanges 19 and is perforated with bolt-holes 20 to receiveconnecting-bolts 13. The outer side of the body is also upwardlyextended, and a reach-rod-pin socket 21 to receive the pin by which thereach-rod is coupled to the reverse-lever is formed in the outer upperextension. The lever-arm 12 is fitted on the lever arm seat 18 betweenand abutting against the lateral flanges 19 thereof and is rigidlysecured to the body either by the connecting-bolts 13, as shown, or inany other suitable known manner, as by being screwed or keyed thereto.The upper end of the leverarm 12 is formed into a handle of suitableform and dimensions to be conveniently grasped by the engineer, and itis provided with a spring-latch of any known and preferred construction,which is adapted to engage the notches of the usual fixed segment andwhich does not form part of my present invention.

While a construction in which the leverarm is formed separately from thebody and is fixed detachably thereto, as in the instance shown, isbelieved to be the preferable one, the lever-arm may, if desired, becast in one piece without departure from the spirit of my invention.

The bearing-pin 16 fits truly in the bearingpin socket 15 of the bodyand is secured to the upper end of a bracket or standard 22, the lowerend of which is secured to one of the frame members 8 of the engine orto any other suitable foundation,the pin 16 thus constituting a fixedbearing on which the reverselever is swung forwardly and backwardly bythe engineer to move the tumbling-shaft in either direction, as desired.

It will be apparent to those familiar with locomotive-engine design andconstruction 7 that a reverse-lever constructed substantially as abovedescribed presents the advantages of being less expensive thanone whichis formed of several connected forged members, of being amply strong andrigid, with a minimum of weight, and of the capacity of ready adaptationin engines of all of the various special designs of the wide or widenedfirebox types in which a cab at the rear end is employed.

I claim as my invention and desire to secure by Letters Patent- 1. In areverse-lever, the combination of an I integral body, which is providedwith a bearing-pin socket at its lower end, a reach-rodpin socketlocated at one side of its upper end and projecting outwardly beyond thebearingpin socket, and a lever-arm fixed to the upper end of the body,on the side thereof opposite the reach-rod-pin socket.

2. In a reverse-lever, the combination of an integral body, which isprovided with a bearing-pin socket at its lower end, a reach-rodpinsocket located at one side of its upper end and projecting outwardlybeyond the bearing-pin socket, and a lever-arm seat at the opposite sideof its upper end, and a lever-arm fitting the lever-arm seat, andsecured thereat to the body.

3. In a reverse-lever, the combination of an integral body, which isprovided with a bearing-pin socket at its lower end, a reach-rodpinsocket located at one side of its upper end and projecting outwardlybeyond the bearingpin socket, and a lever-arm seat at the opposite sideof its upper end, and a lever-arm fitting the lever-arm seat and secureddetachably to the body.

4. In a reverse-lever, the combination of an integral body, which isprovided with a bearing-pin socket at its lower end, a reach-rodpinsocket located at one side of its upper end and projecting outwardlybeyondthe bearingpin socket, and a laterally-flanged lever-arm seat atthe-opposite side of its upper end, and a lever-arm fitting on thelever-arm seat and abutting on the lateral flanges thereof and secureddetachably to the body.

5; In a reverse-lever, the combination of an integral cast-metal body,which is provided with a bearing-pin socket at its lower end, areach-rod-pin socket located at one side of its upper end and projectingoutwardly beyond the bearing-pin socket, a lever-arm seat at theopposite side of its upper end, and strengthening edge flangesconnecting its sockets one with the other and with the leverarm seat,and a lever-arm fixed to the body at the lever-arm seat.

6. In a reverse-lever, the combination of an integral platereverse-lever body, which is provided with a bearing-pin socket at itslower end, a reach-rod-pin socket located at one side of its upper endand projecting outwardl y beyond the bearing-pin socket, a bearing-pinsecured to a fixed support and fitting the bearing-pin socket, and alever-arm fixed to the upper end of the body on the side thereofopposite the bearing-pin socket.
